REVOLVING HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 224,718, dated February 1*?, 1880.

Application ilcd October 11` 1879.

To all whom t may concern:

Be it known that I, JACOB S. OBERHOLT- ZER, of Wadsworth, in the county of Medina and State of Ohio, have invented a new and Improved Revolving Hay-Rake, of which the following is a specification. j Figure 1, Sheet 1, is a plan view of my hayrake. Fig 2, Sheet 1, is a side sectional elevation of the rake, taken through the line xx, Fig. 1. Fig. 3, Sheet 2, is a side elevation, partly in section through the line y y, Fig. l.

Similar letters of reference indicate corresponding parts. j

The object of this invention is to furnish a revolving hay-rake so constructed that the rake-head may be raised to l#pass obstructions and miss hay without discharging the collected hay, may be conveniently adjusted with the teeth at any desired inclination, and may be readily tripped to discharge collected hay.

The invention consists in the combination, in a revolving hay-rake, of various attachments with the rake-head and sulky, so that the rake-head may be readily adjusted and controlled, as hereinafter fully described.

Aare the wheels, and B the axle, of the snlky. To the forward side of the axle B are hinged the thills C. To the thills C, at or near the ends of their forward cross-bar, D, are hinged the forward endssof the draw-bars E. VThe draw-bars E pass back above the axle B, and their rear parts are curved downward, and have their ends bent upward into U form to receive and serve asbearings for the shaft of the rake-head F. The shaft of the rakefhead F is secured in place in the bends of the draw-bars E by blocks Gr secured to the draw-bars E above the said shaft.

H are two levers, the lower parts of which are bent forward, and their ends are bolted to the rear side of the axle B. To the levers H, at or near their bends, are attached pins I,

. which project beneath the lower edges of the J is a lever, the lower end of which is secured to the shaft `of the rake-head F by a lmetal strap, K, passing around the said shaft and attached to the said lever. The bent part of the strap K is slotted longitudinally for the passage of-the stop-pinL, attached to the shaft of the rake-head F, and which 'moves through the said slot when the rake-head F revolves.

To the front and rear sides ot' the lower part of the lever J are attached springs R, the lower ends of which rest against the projecting ends of the pin L, so that the rake-head F may be adjusted and held in place by means of the lever J.

To the upper part of the lever J is pivoted the rearrend of a rod, M, the forward end of which is pivoted to the upper part of a lever, N. The lower end of the lever Nis slotted to receive the ratchet-plate O, attached to the rear crossbar, l?, ofthe thills C, and is pivoted to said plate by a pin or bolt. With the lower part of the lever N is connected a sliding pawl, Q, to engage with the teeth of the ratchetplate Oand lock the lever N in place when adjusted.

'By this arrangement the rake-head F inay be adjusted to give any desired inclination to the rake-teetlnand to cause them to catch upon the ground and revolve to discharge the collected hay by operating the lever N. v

To the side of the lever J is pivoted a lever, S, the lower end of which is bent to one side to pass in between the lever J and the rear spring, R.

The lever S is made shorter than the distance between the rake-head F and the end of the connecting-rod M, and has a hole through it to receive a rod, T. The rear end of the rod T has a head or other stop formed upon or attached to it to prevent it from being drawn out of the hole in the lever S. The forward end of the rod T is pivoted to the lever N.

The rod T is made enough longer than the rod M to allow the lever N to be moved back and forth in adjusting the rake-head without bringin g the stop upon the rear end of the rod- T in contact with the lever S 5 but should the lever N be moved sofar forward as to bring the forward ends of the rake-teeth into con- IOO tact with the ground the rod T Will operate the lever S to raise the spring' R from the pin L and allow the rake-head F to revolve.

Having thus described my invention, what 2. The combination,in a revolving hay-rake, of the lever S and the sliding rod T With the levers M N and spring-catch R, substantially as herein shown and described, so that the rake-head F may be released automatically 2o and allowed to revolve when its teeth have been brought to a 'lixed inclination, as set forth.
